Description

Eprosartan-D3 is a deuterium-labeled analog of the antihypertensive drug Eprosartan, specifically designed for use as an internal standard in quantitative analytical methods. This high-purity stable isotope-labeled compound is essential for ensuring the accuracy and reliability of mass spectrometry-based analyses, particularly in pharmacokinetic and bioequivalence studies. It is a critical material for pharmaceutical research and development laboratories, contract research organizations (CROs), and quality control departments requiring precise quantification of Eprosartan in complex biological matrices.

Application

• Primary use as an Internal Standard for the quantification of Eprosartan via LC-MS/MS and GC-MS.
• Method development and validation in Bioanalytical Research for drug metabolism and pharmacokinetics (DMPK) studies.
• High-accuracy analysis in Clinical Trial sample testing to determine drug concentration levels in plasma, serum, or urine.
• Quality control and assurance in pharmaceutical manufacturing for batch analysis of Eprosartan active pharmaceutical ingredient (API) and finished dosage forms.
• Use in forensic and anti-doping laboratories for confirmatory analysis.
• Application in environmental testing methods for trace analysis, where labeled standards are required for precise calibration.

Quality Control

Our Eprosartan-D3 is manufactured under strict quality control protocols to ensure the highest isotopic purity and chemical integrity required for analytical applications. Each batch is characterized by advanced spectroscopic and chromatographic techniques, including NMR, HPLC, and mass spectrometry, to confirm identity, chemical purity, and isotopic enrichment. A comprehensive Certificate of Analysis (COA) is provided, detailing all critical specifications. We support compliance with GMP/GLP guidelines for research and regulatory submission purposes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to minimize exposure to atmospheric humidity. For long-term storage, consider storing under an inert atmosphere.
